Access Modifiers

  private   - can only be accessed from inside of the class

  default (no keyword is used) - can be accessed from anywhere
                                  inside of the classes "package"
                                  (This default mode screws up Java)

  protected - can only be accessed from inside of the class
                 or from a class that inherits this class

  public    - can be accessed by any code

To compile Java Code:

Source code:   Point2d.java

To compile:    javac Point2D.java

  Compilation creates a file called Point2d.class

To run the class file, we type:  java Point2d   

In Java:  the new operator is similar to malloc
            Everything (except primitives) are references/pointers
